ABSTRACT:
A Josephson junction consisting of high temperature ceramic superconductors layers, separated by an ultra-thin insulating barrier made of an non oxide substance like diamond-like carbon, is described. An integral part of this disclosure is the technique involving the use of an activated oxygen species for providing an oxygen chemical potential which is higher than that obtainable at barometric pressure. Also clarified are the structure and method of manufacturing the said junction, using high temperature superconductors.
